What to say about the freshwater mussel Rectidens?

It is another one of those taxa for which a google search returns a bunch of sources that merely notice its existence. We already knew that from the global reviews of Simpson (1900, 1914), Haas (1969) and Graf & Cummings (2007).

R. lingulatus is restricted to Borneo.
